TLV7044RTER

Texas Instruments · Comparators · WQFN-16(3x3)

TLV7044RTER from Texas Instruments, in a WQFN-16(3x3). Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 +IN A input Noninverting input for channel A; the input common-mode range extends from VEE - 0.1 V to VCC + 0.1 V.
2 VCC power_in Positive (highest) supply; VS = VCC - VEE must be within 1.6 V to 6.5 V (1.2 V minimum for the S and L options), with an absolute maximum of 7 V.
3 NC unconnected No internal connection.
4 +IN B input Noninverting input for channel B; if the input swings 0.3 V below VEE it must be current-limited to 10 mA or less.
5 -IN B input Inverting input for channel B; inputs are diode-clamped to VEE and the absolute input range is VEE - 0.3 V to 7 V.
6 OUT B output Open-drain output for channel B (TLV704x), which can be pulled up to an external source up to 6.5 V independent of the supply voltage; absolute maximum is VEE - 0.3 V to 7 V.
7 OUT C output Open-drain output for channel C (TLV704x), which can be pulled up to an external source up to 6.5 V independent of the supply voltage; absolute maximum is VEE - 0.3 V to 7 V.
8 -IN C input Inverting input for channel C; inputs are diode-clamped to VEE and the absolute input range is VEE - 0.3 V to 7 V.
9 +IN C input Noninverting input for channel C; if the input swings 0.3 V below VEE it must be current-limited to 10 mA or less.
10 NC unconnected No internal connection.
11 VEE power_in Negative (lowest) supply or ground for single-supply operation.
12 +IN D input Noninverting input for channel D; if the input swings 0.3 V below VEE it must be current-limited to 10 mA or less.
13 -IN D input Inverting input for channel D; inputs are diode-clamped to VEE and the absolute input range is VEE - 0.3 V to 7 V.
14 OUT D output Open-drain output for channel D (TLV704x), which can be pulled up to an external source up to 6.5 V independent of the supply voltage; absolute maximum is VEE - 0.3 V to 7 V.
15 OUT A output Open-drain output for channel A (TLV704x), which can be pulled up to an external source up to 6.5 V independent of the supply voltage; absolute maximum is VEE - 0.3 V to 7 V.
16 -IN A input Inverting input for channel A; inputs are diode-clamped to VEE and the absolute input range is VEE - 0.3 V to 7 V.
17 EP passive Exposed pad (from the footprint; not named in the datasheet pin table).
